[kwin] [Bug 449957] KWin crash when turning off or unplugging monitor
https://bugs.kde.org/show_bug.cgi?id=449957 --- Comment #6 from phrxmd --- In addition, when KWin comes back up again from the crash, the Plasma wallpaper is scaled incorrectly on a HiDPI display - as if it has the scaling factor for that monitor applied twice. It's as if before the crash there was a cached version of the wallpaper with the HiDPI scaling, and after the crash, when KWin comes up again, it reads the cached wallpaper and applies the HiDPI scaling to it again. See bug 445160 for photos of the desktop arrangement before and after the crash. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=449957 --- Comment #4 from Mircea Kitsune --- I only know I'm waiting for at least 3 years on the Wayland session to fix issues with monitor standby. The one and only reason I'm still stuck on X11 is everything crashes when my monitor goes into power saving, which I must enable to conserve power and preserve the screen. Even when it doesn't crash by some miracle, the monitor immediately wakes back up after powering down so power saving still won't work. HDMI and DisplayPort both do this. Whatever it is, please try to fix it in the upcoming Plasma 5.24! Thank you. -- You are receiving this mail because: You are watching all bug changes.

What would > be the best way to get a backtrace or detailed log output? There are a couple of ways to get the backtrace: * check coredumpctl, `coredumpctl list kwin_wayland && coredumpctl gdb `, then type "bt" in gdb. make sure that debug symbols are installed * attach a debugger to kwin_wayland process and try to reproduce the crash, when kwin crashes, type "bt" in gdb.
